Button Activation
On On Turn lights on.
Off Off Turn lights off.
Walk test Off On Off When set to On this causes a red LED to flash on
the sensor when it detects movement. Use this
feature to check for adequate sensitivity levels.
Time Out
(Time

minutes 10
seconds Once the detector is turned on, this value sets
how long the lights will stay on once movement
has ceased.
Lux on
level
(Switch
level on) 9 2, 5 & 7 4, 6 & 9 Lux level setting to prevent the luminaires being
switched on if the ambient light level is sufficient
(adjustable between 1 and 9). The luminaires will
always be switched on at level 9.
Lux off
level
(Switch
level off) 9 2, 5 & 7 4, 6 & 9 Lux level setting to switch the luminaires off during
occupancy if the ambient light level goes above
the setting (adjustable between 1 and 9). Level 9
will always keep the lights on. This setting can be
used for “window row switching”.
Note: the Lux Off Level value must always be
greater than the Lux On Level value.
Sensitivity 9 1, 5 & 9 3, 6 & 8 Sensitivity level for detecting movement.
1 = low sensitivity
9 = high sensitivity
Defaults D Returns the unit to the default settings.
Presence /
Absence Presence Presence Absence Presence mode allows the output to turn on when
movement is detected and off when movement
ceases. Absence mode allows the output to turn
off when movement ceases, but must be manually
turned on first.
Shift Use this button to select the settings in red and
blue signified by the ‘Shift 1’ and ‘Shift 2’ LEDs

The functionality of the MWS3A-PRM-LV is controlled by a number of parameters which can
be changed or programmed by any of the following devices:
 UHS5 Infrared Handset. See below for programmable functions.
 UNLCDHS Infrared Handset (with LCD). See user guide for full programming details.
For most basic programming operations the UHS5 handset can be used and the following procedures
are based on using this device.
Point the handset at the Sensor and send the required programming commands to the unit as shown
below.
Valid commands will be indicated by a red LED flash. See page 1 for details of other LED responses.
Note: other functions on the UHS5 which are not shown below are not applicable to this product.

What if the load does not turn ON?
 Check that the supply to the circuit is good.
 If the detection range is smaller than expected, check the diagram on page 2. Adjusting the angle of the sensor head
slightly may improve the detection range. If still reduced it may be compromised by the ceiling construction /
material. Add the supplied 20mm spacer ring. See page 4 for fitting details.
HINT: The Walk Test LED function can be used to check that the unit is detecting movement in the required area.
What if the load does not turn OFF?
 Ensure that the area is left unoccupied for longer than the Time Out Period.
 Ensure that the sensor is not adjacent to circulating air, heaters or lamps.
